Inside the latest issue of the mag, Kourtney describes what its like being a mommy to baby Mason Dash Disick: “I feel so lucky. He’s such a good baby.”

Kourtney was also asked about her baby’s controversial middle name — Dash (the name of the clothing store of the Kardashian sisters). She explains, “Dash is not for my clothing store, as some people have suggested online. That would be stupid. Dash is short for Kardashian, and it was my father’s nickname.”

There are also rumors that Kourtney freaked out recently when she found out that Kim Kardashian‘s NFL boyfriend, Reggie Bush, was planning to propose to Kim during the holidays. Apparently Kourtney was none too pleased as she wanted the holidays to be all about she and her new born baby.

According to the National Enquirer, “Reggie doesn’t want to battle Kourtney, so he backed off to keep the peace.” The story claims Reggie is now planning on proposing to Kim in early 2010.
